It’s very easy to quote too often from others but I love this one also, from the same source Ben Hardy: “Investing in yourself creates internal supply to match the external demand of the investment. The bigger you invest, the bigger the psychological leap — which then facilitates a radical upgrade in behavior, confidence, harmonious passion, and outcomes.”
The same way you won’t get bigger or stronger lifting 5kg weights every month or so at the gym, you won’t improve or develop if you don’t take a big step and put yourself under more pressure. You won’t get stronger, if you don’t put yourself under the weight. And one more cliché for you, if you don’t challenge yourself you will not change. So take a big step.
